NMEA Releases OneNet Ethernet Standard

Updated: Nov 13, 2021

The National Marine Electronics Association (NMEA) has released its latest protocol, the NMEA OneNet® Standard, Version 1.000.

This is an open industry standard based on Internet Protocol Version 6 (IPv6) and the IEEE 802.3 Ethernet Local Area Network. The standard brings together years of committee efforts and is designed for standardized IP networking of marine electronic devices on and off the vessel.


OneNet provides a common network infrastructure for marine electronic devices and/or services on IPv6. All OneNet application protocols, such as NMEA 2000® PGN messages, are designed to use a standard IPv6 network protocol stack. The NMEA OneNet Committee utilized many existing standards, including RFCs (Requests for Comments) published by the Internet Engineering Task Force (IETF). Th
